WILSON HOLES, OF INDIANABQLIS, INDIANA.

Application filed November 17, 1 e22.--- Serial No, 301,525." 7 l To all whom a may 6mm.- 2

Be itfknown that I, WILSON Norms, a,

citizen ofethe United States, residing atIndianap'ol'is, in the county of Marion and State of Indiana, have invented new and 'useful Improvements in Filters, ofv which the following isaspecification,

.vThis invention relates to and has for its ob" ct the provision of a novel filter designe a water cooler.jor-:other receptacle and operating to continuously filter the water automatically so' that'all impurities and foreign Animportan't and more specific object is: the prov sion of a filtering device of this character which includes a receptacle within which the water, together with ice if preferred, is placed, the receptacle being pro.-

vided in itsbottom and also at spaced points along its sides with filtering elements.

An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture, highly efiicient in use, durable in service and a general improvement in theart.

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure l is a vertical section through my device mounted within a water cooler,

Figure 2 is a plan view, the cover of the cooler being removed,

Figure 3 is a horizontal section.

Referring more particularly to the drawings the letter A designates a'water cooler of any ordinary or' preferred type naturally provided with a cover and an outlet spigot. In carrying out-my invention I provide an elongated cylindrical receptacle 1O constructed of galvanized iron, tin or other suitable material and suspended within the cooler A as for instance by having its bead 11 engaged upon lugs 12 which project from the inner periphery of the cooler. v Any other equivalent holding means may be provided if preferred.

In order to facilitate handling of this receptacle, it is provided with-a bail 13 which has its ends engaged within ears 14 on the inner periphery of the receptacle and this hail normally =.ts upon either one of a pair to bemounted within 7 ruct ng of .l'ugs 15=which areon, the inside of the receptacle near the top thereof I Extending inwardly from then-inner' periphery of the receptacle at pointssomewhat below the top areilugs l ti which constitute a support for a somewhattapered removable shelf 17 which is adapted'. to support ice and filtering deviceswhich is formed. in the center-of its bottom with a hole 18.

The lower-end of the receptacle open and formed with-a retaining "flange 19 ,upon

to 'act as a filter...: Thisqdisk is of course securelycemented inplace. ,in addition to being heldby the-flange.- A

which restsra disk 20r.of .natural stone or other material of a sufiiciently porous nature matter will be removed'and the water con sequently made fit for drinking purposes.-

place and it will be apparent that there is provided a space 24 between each frame and they wall of the receptacle. The receptacle is formed with h s 25 which communicate with the spaces 21.

'In the use of the device it will be apparent that when the receptacle is suspended within a water cooler and water, together with ice if desired, placedwithin the receptacle, it is apparent that the water will seep through the disk 20 at the bottom of the receptacle and drop into the cooler. At the same time the water will seep through the blocks 22 and accumulate within the spaces 24: from which it will ,flow through the holes 25. In this way it is apparent that the filtering action will be complete and automatic as well as sufiiciently rapid to filter a proper quantity of water in a reasonably short time. Whenever it is necessary the receptacle may be washed out thoroughly to remove any accumulation on the filtering disk or blocks so that the device will be kept in a thoroughly sanitary condition.

While I have shown and, described the preferred embodiment of the invention it is of course to be understood that I reserve the righttomake such changes in the form, d a rran'gement of parts as V receptacle suspendediwithin the outer re-- will not depart from the spirit of the invention or the scope of the subjoined claims. Having thus described -my invention I claim: r

1. A i filtering device comprising an outer receptacle provided .with a drain, an inner j inner receptacle having its wall provided with openings communicating with said a '2. A device of the character described 20 compartments.

comp-rising adouble walled outer receptacle having a. removable cover and provided at its bottom with-a draw oifcock, a plurality fof brackets secured .on the inner periphery -'of said outer receptacle near the top' thereof and a'rran'gedin equally spaced relation, an

inner receptacle provided at its upper edge" with a bead engaging upon said brackets whereby to efi'ect suspension of the. inner receptacle, a tray within the inner receptacle for holding a block of ice, and filtering means at the bottom and at the sides of the inner receptacle.

'3. A filtering device comprising a recep tacle formed inits'vside with spaced holes, and frames secured upon the innerperiphery and defining spaces communicating withsaid holes, each frame carrying a block of filtering material, each frame being formed as a flat plate having its side edges lyin against the inner wall of the receptacle an having its upper and lower edges'formed with curved fianges'conformingly engaging the receptacle, and each frame. being furthermore formed with an openingsurrounded by a retaining flange for the filtering material.

In testimony whereof I afiix my signature.
